Operation
Printed in U.S.A. 77 50940411/G0219
Warm Up
Operating the work hydraulics before the
hydraulics are warmed up is dangerous,
because response will be slow and the machine
might move in unexpected ways. Additionally,
operating the machine before proper warm-up
can also damage the machine. Be sure to
sufficiently warm up the machine before starting
work.
IMPORTANT: Do not operate the control joysticks
suddenly until the hydraulic oil has reached operat-
ing temperature.
1. After starting, allow the engine to run at low idle
for a minimum of 5 minutes with no load (no
drive, lift, tilt or auxiliary hydraulic functions).
NOTE:
On models RT175 and RT210 with
Tier 4 engines, low engine idle speed is
increased to 1100 rpm until engine reaches
operating temperature.
2. Run the engine at 1800 rpm with no load for 5
minutes.
3. Raise the lift arm so the attachment is off the
ground.
4. Extend and retract each of the cylinders several
times with no load.
5. Travel slowly forward and backward several
times.
6. Additionally, in cold weather, tilt the attachment
all the way forward and keep it there for 20-25
seconds. Repeat this step until the attachment tilt
speed is normal.
NOTE:
Engine speed may be limited during a cold
start and/or during a travel drive error condition.
See “Travel Drive Error Condition Operation (Limp
Mode)” on page 94.
Run-In Period
The performance and service life of the machine is
heavily dependent on using the machine carefully
during its first 100 operating hours.
• Do not operate machine at the maximum rated
operating capacity.
• Do not run the engine at a high speed for
extended periods of time.
• Increase the load gradually while varying the
engine speed.
• Follow the maintenance schedule. See “Mainte-
nance Schedule” on page 123.
Stopping the Engine
Perform the “Mandatory Safety Shutdown
Procedure” on page 20.
IMPORTANT:
Do not stop the engine at full throt-
tle. Damage to the engine can result. Allow the
engine to idle for approximately 2 minutes before
shutting it off.
